38mm Sudco Racing Carb Keihin questions?

[Dustin88]

I just bought a superjet that was an old race ski. I has a 62t/61x motor this two blue sudco racing keihen carbs(i think 38mm). Anyone know anything about this carbs?

Theres a sticker on them saying sudco, race only carb.

What really you asking about ?

I was just wondering if there is an advantage to running these carbs over the stock 38mm mukuni carbs. I was just trying to figure out why someone would buy these carbs and a intake adapter when the engine already came with two 38mm carbs?

Thay may be 40mm carbs

If they're blue, they will be 42mm carbs.

They are blue, I guess I was wrong, buying 42mm carbs makes more sense! I was told they were 38mm carbs but I can see where the intake manifold was bored out so that makes sense!
Now if I can just figure out why this ski has 6 pissers!
Thanks

Group K use to say that they 42's were some of the only aftermarket carbs that they supported (words to that effect).
